Dai Funka: Akainu's signature technique, he transforms his fists into pure lava before throwing it forward, like an over-sized rocket (similar to Luffy's Gomu Gomu no Gigant Pistol or Ace's Hiken). The explosion causes volcanic rock to hit the ground, in a method similar to meteors.

Ryusei Kazan: Akainu creates a great number of magma fists that he fires into the air in order to let them rain down upon the battlefield, causing enormous amounts of area damage. This looks like a cross between a meteor shower and a volcanic eruption.

Inugami Guren: Akainu creates a wave of magma, shaped like a dog's head, and launches it against his opponent.

Meigo: Akainu transforms his hand into magma and lashes out at the opponent with a claw-thrust. This technique is powerful enough to tear off half of Whitebeard's face with a glancing blow. In the anime, in order to severely censor the gore of Whitebeard's face being torn in half, this technique's execution and function are different: Akainu punches into his opponent's body with a molten fist in a stance similar to Dai Funka, and then detonates it, causing massive internal damage.

Kazan Bakuhatsu: Sakazuki transforms his hand into magma, and then punches the ground. This results in an eruption of volcanic rocks around the punch area and several spots around it, inflicting damage to anyone within the blast radius.
